CL is a learning method that enables students to work in groups of four to six and interdependently create their own learning (Slavin, 1987). It is a constructivist model of learning; as a result, it requires the students to explore information and puts students at the center of learning process (Wadsworth, 1996). It does not ask teachers to teach the students, but instead to direct them to the sources of information. This way, the students create their own learning. CL, on the other hand, enhances the aim of Constructivism and enables teachers to ensure that each student has reached the target learning level. To do this, teams of four to six are created and interdependence is generated so that the group members help each other reach the target.
